[0010001111]... Hello User... [1001010101]
Here's your answer...

No. of balls = 20, so total outcomes = 20
a) Odd numbers from 1 to 20 = {1,3,5,7,9,11,13,15,17,19}
No. of favourable outcomes = 10
Probability = 10/20 =1/2

b) Numbers not divisible by 10 = {1,2,3,4,5,6,7,8,9,11,12,13,14,15,16,17,18,19}
No. of favourable outcomes = 18
Probability = 18/20 = 9/10

c) Multiple of four = {4,8,12,16,20}
No. of favourable outcomes = 5
Probability = 5/20 = 1/4

d) A number divisible by 2 and 3
= A number divisible by 6 = {6,12,18}
No. of favourable outcomes = 3
Probability = 3/20
